An Argentine passport for Americans: what changes, and what does not

US citizens can add Argentine nationality without giving anything up. The gains are real but narrow, and the IRS will see no difference at all.

Key facts

  • Cost: US$350,000 non-refundable contribution, or a US$800,000 government bond. A family of four starts at US$500,000.
  • The United States permits dual nationality. You keep your US passport and must use it to enter and leave the US.
  • US tax: nothing changes. Worldwide taxation, FBAR and FATCA reporting continue.
  • Travel gains are narrow: Brazil and mainland China are the clearest. Mercosur residence rights come only after five years as an Argentine.
  • Legal status: the decree behind the programme is under appeal at Argentina's Supreme Court. See legal status.

Americans hold one of the strongest passports in the world. So the question for a US citizen is not “where can I go?” but “what does a second nationality add to my life, my family and my options?” For most Americans, the honest answer is a South American base, a fallback document and some specific travel gains. It is not a tax strategy.

This guide covers the US-specific points. For the programme itself, start with our overview of Argentina citizenship by investment and the full cost breakdown.

Note. Two Argentine appeal courts have ruled against DNU 366/2025, the decree that allows naturalisation through investment. On 18 June 2026 Chamber III of the federal civil and commercial appeals court struck down the parts that give citizenship decisions to Migraciones. On 30 June 2026 the Cámara Nacional Electoral declared the decree unconstitutional. The government has appealed to the Supreme Court and says the decree stays in effect until the ruling is final. Read our legal status page before you commit funds.

Does the United States allow dual citizenship?

Yes. US law accepts dual nationality, although the State Department says it does not encourage it. Under 8 U.S.C. §1481, naturalising in another country causes loss of US nationality only when the act is voluntary and done with the intention of relinquishing US citizenship. Applying for Argentine citizenship to add a passport does not meet that test.

Two practical rules follow:

  • US passport for US borders. Federal law (8 U.S.C. §1185(b)) requires US citizens to enter and depart the United States on a US passport.
  • Argentina sees you as Argentine. Inside Argentina, the local authorities treat you as an Argentine national. Plan to carry Argentine documents when you travel there.

Argentina also allows multiple nationality, so neither side asks you to renounce anything. Our dual citizenship guide covers the Argentine side in more detail.

Mobility: where an Argentine passport helps an American

The July 2026 edition of the Henley Passport Index places the US passport 10th, with 180 visa-free or visa-on-arrival destinations. The Argentine passport ranks 16th, with 169. On paper, therefore, Americans gain almost nothing. In practice, a few gaps matter.

Destination US passport Argentine passport
Brazil Visa required (e-visa) No visa; entry with Argentine ID card
Mainland China Visa required (240-hour transit and Hainan exceptions only) 30 days visa-free until 31 Dec 2026
Schengen Area 90 days in 180 90 days in 180 (same)
United States Home country B1/B2 visa required (not in the Visa Waiver Program)
Canada No visa Visa required (eTA only in limited cases)

Brazil’s official visa table, updated in August 2026, lists the United States as “visa required” and Argentina as visa-free with entry on a civil identity card. China’s National Immigration Administration lists the US only for 240-hour transit and Hainan’s regional scheme, while Argentines currently enter the mainland visa-free for 30 days.

Residence is a longer-term gain. The Mercosur Residence Agreement lets nationals of member states apply for two-year temporary residence in Brazil, Uruguay, Chile, Colombia and others. But Article 2 covers naturalised nationals only after they have held that nationality for five years, so an investor-citizen cannot use it at once. In the meantime, the Argentine national identity card (DNI) is accepted as a travel document in Bolivia, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru and Uruguay.

What the Argentine passport does not give you: easier access to the United States or Canada, or an EU right of residence. Spain’s two-year naturalisation route for Ibero-American nationals applies only to Argentines by origin, not to naturalised citizens. See our passport guide for the full picture.

US tax and reporting: nothing changes

The United States taxes on citizenship, not residence. The IRS states that US citizens living abroad are taxed on their worldwide income from all sources. Adding Argentine nationality does not change this, and no tax treaty softens it: the IRS list of US income tax treaties has no entry for Argentina.

Your existing obligations continue:

  • FBAR (FinCEN 114). You must file if your foreign financial accounts exceed US$10,000 in aggregate at any time in the year. It is due 15 April, with an automatic extension to 15 October.
  • Form 8938 (FATCA). A single filer living in the US reports specified foreign financial assets above US$50,000 at year-end or US$75,000 at any time. A single filer living abroad uses US$200,000 and US$300,000.
  • The bond route. A US$800,000 Argentine government bond is a foreign financial asset. Ask your adviser how to report it, and how its zero coupon is treated.

Argentina and the United States have a Model 1 FATCA agreement, in force since 1 January 2023. Argentine banks therefore report accounts held by US persons to the IRS through Argentina’s tax authority.

Two further points are often misunderstood:

  • The contribution is not deductible. IRS Publication 526 names only US governmental units as qualifying government recipients and excludes most foreign organisations. A payment to Argentina’s National Treasury does not qualify.
  • There is no exit tax. The expatriation tax under IRC §877A applies only to citizens who renounce. If you keep your US citizenship, it does not apply.

On the Argentine side, people naturalised through investment do not become Argentine tax residents only because of their new nationality. The ordinary residence rules apply, as explained in our cost guide.

Due diligence: what an American file looks like

Argentina’s checks cover identity, the traceability and legality of funds, financial and asset analysis, jurisdictional risk, criminal and reputational background, and migration history. The standard is aligned with the OECD and the FATF, and all funds must move through the formal financial system.

The United States is not on the FATF list of jurisdictions under increased monitoring. US applicants should still expect detailed source-of-funds questions, especially for wealth from business sales, private funds or digital assets.

Practical steps: banking, apostilles and translation

Banking. A US$350,000 wire is routine for a private bank, but expect compliance questions about the recipient. Keep the paper trail: sale documents, brokerage statements and tax returns that show where the money came from.

Apostilles. The United States has been a member of the Hague Apostille Convention since 1981, and Argentina since 1988. For the documents you will need:

  • Federal documents, such as an FBI Identity History Summary: the Department of State’s Office of Authentications.
  • State documents, such as birth and marriage certificates: usually the Secretary of State of the issuing state.

Translation. Budget for certified Spanish translations of every English document. The programme’s document rules were not yet published as of 2 October 2026, so confirm the format with Argentine counsel before you translate.

Is it right for you?

It may suit you if:

  • You want a long-term residence option in South America, or you already spend time in the region.
  • You want a second document for travel to Brazil or China, or for family members.
  • You value a fallback nationality and accept that it carries no US tax benefit.

It is probably not right for you if:

  • Your main goal is to reduce US tax. It will not.
  • You want EU residence rights. Argentina does not give them.
  • You cannot accept legal uncertainty while Argentina’s Supreme Court considers the decree.

Every case is personal. Speak to a qualified US tax adviser and Argentine counsel before you commit, or request a private briefing.

Frequently asked questions

Will I lose my US citizenship if I become Argentine?

No. US law treats naturalisation abroad as a loss of nationality only if it is done voluntarily with the intention of giving up US citizenship. Holding both is lawful, although the US government does not encourage it.

Does Argentine citizenship reduce my US taxes?

No. The United States taxes its citizens on worldwide income wherever they live, and there is no US–Argentina income tax treaty. FBAR and Form 8938 reporting continue as before.

Is the US$350,000 contribution tax-deductible in the US?

No. IRS Publication 526 limits deductible gifts to US governmental units and qualifying organisations. A payment to a foreign government's treasury does not qualify.

Can I enter the United States on my Argentine passport?

No. US citizens must enter and leave the United States on a US passport. Argentina is also not in the Visa Waiver Program, so the Argentine passport alone would require a B1/B2 visa.

Where does an Argentine passport help an American traveller?

Mainly in South America and China. Argentines enter Brazil with a national identity card, while Americans need a Brazilian visa, and Argentines currently have 30 days visa-free in China until 31 December 2026.
